This is the Django template system.
How it works:
The Lexer.tokenize() method converts a template string (i.e., a string
containing markup with custom template tags) to tokens, which can be either
plain text (TokenType.TEXT), variables (TokenType.VAR), or block statements
(TokenType.BLOCK).
The Parser() class takes a list of tokens in its constructor, and its parse()
method returns a compiled template -- which is, under the hood, a list of
Node objects.
Each Node is responsible for creating some sort of output -- e.g. simple text
(TextNode), variable values in a given context (VariableNode), results of basic
logic (IfNode), results of looping (ForNode), or anything else. The core Node
types are TextNode, VariableNode, IfNode and ForNode, but plugin modules can
define their own custom node types.
Each Node has a render() method, which takes a Context and returns a string of
the rendered node. For example, the render() method of a Variable Node returns
the variable's value as a string. The render() method of a ForNode returns the
rendered output of whatever was inside the loop, recursively.
The Template class is a convenient wrapper that takes care of template
compilation and rendering.
Usage:
The only thing you should ever use directly in this file is the Template class.
Create a compiled template object with a template_string, then call render()
with a context. In the compilation stage, the TemplateSyntaxError exception
will be raised if the template doesn't have proper syntax.
Sample code:
>>> from django import template
>>> s = '<html>{% if test %}<h1>{{ varvalue }}</h1>{% endif %}</html>'
>>> t = template.Template(s)
(t is now a compiled template, and its render() method can be called multiple
times with multiple contexts)
>>> c = template.Context({'test':True, 'varvalue': 'Hello'})
>>> t.render(c)
'<html><h1>Hello</h1></html>'
>>> c = template.Context({'test':False, 'varvalue': 'Hello'})
>>> t.render(c)
'<html></html>'

Accessors for related objects.
When a field defines a relation between two models, each model class provides
an attribute to access related instances of the other model class (unless the
reverse accessor has been disabled with related_name='+').
Accessors are implemented as descriptors in order to customize access and
assignment. This module defines the descriptor classes.
Forward accessors follow foreign keys. Reverse accessors trace them back. For
example, with the following models::
class Parent(Model):
pass
class Child(Model):
parent = ForeignKey(Parent, related_name='children')
``child.parent`` is a forward many-to-one relation. ``parent.children`` is a
reverse many-to-one relation.
There are three types of relations (many-to-one, one-to-one, and many-to-many)
and two directions (forward and reverse) for a total of six combinations.
1. Related instance on the forward side of a many-to-one relation:
``ForwardManyToOneDescriptor``.
Uniqueness of foreign key values is irrelevant to accessing the related
instance, making the many-to-one and one-to-one cases identical as far as
the descriptor is concerned. The constraint is checked upstream (unicity
validation in forms) or downstream (unique indexes in the database).
2. Related instance on the forward side of a one-to-one
relation: ``ForwardOneToOneDescriptor``.
It avoids querying the database when accessing the parent link field in
a multi-table inheritance scenario.
3. Related instance on the reverse side of a one-to-one relation:
``ReverseOneToOneDescriptor``.
One-to-one relations are asymmetrical, despite the apparent symmetry of the
name, because they're implemented in the database with a foreign key from
one table to another. As a consequence ``ReverseOneToOneDescriptor`` is
slightly different from ``ForwardManyToOneDescriptor``.
4. Related objects manager for related instances on the reverse side of a
many-to-one relation: ``ReverseManyToOneDescriptor``.
Unlike the previous two classes, this one provides access to a collection
of objects. It returns a manager rather than an instance.
5. Related objects manager for related instances on the forward or reverse
sides of a many-to-many relation: ``ManyToManyDescriptor``.
Many-to-many relations are symmetrical. The syntax of Django models
requires declaring them on one side but that's an implementation detail.
They could be declared on the other side without any change in behavior.
Therefore the forward and reverse descriptors can be the same.
If you're looking for ``ForwardManyToManyDescriptor`` or
``ReverseManyToManyDescriptor``, use ``ManyToManyDescriptor`` instead.

In the above, if ``athlete_list`` is not empty, the number of athletes will
be displayed by the ``{{ athlete_list|count }}`` variable.
The ``if`` tag may take one or several `` {% elif %}`` clauses, as well as
an ``{% else %}`` clause that will be displayed if all previous conditions
fail. These clauses are optional.
``if`` tags may use ``or``, ``and`` or ``not`` to test a number of
variables or to negate a given variable::
{% if not athlete_list %}
There are no athletes.
{% endif %}
{% if athlete_list or coach_list %}
There are some athletes or some coaches.
{% endif %}
{% if athlete_list and coach_list %}
Both athletes and coaches are available.
{% endif %}
{% if not athlete_list or coach_list %}
There are no athletes, or there are some coaches.
{% endif %}
{% if athlete_list and not coach_list %}
There are some athletes and absolutely no coaches.
{% endif %}
Comparison operators are also available, and the use of filters is also
allowed, for example::
{% if articles|length >= 5 %}...{% endif %}
Arguments and operators _must_ have a space between them, so
``{% if 1>2 %}`` is not a valid if tag.
All supported operators are: ``or``, ``and``, ``in``, ``not in``
``==``, ``!=``, ``>``, ``>=``, ``<`` and ``<=``.
Operator precedence follows Python.

Regroup a list of alike objects by a common attribute.
This complex tag is best illustrated by use of an example: say that

``instrument`` attributes, and you'd like to display a list that
looks like:
* Guitar:
* Django Reinhardt
* Emily Remler
* Piano:
* Lovie Austin
* Bud Powell
* Trumpet:
* Duke Ellington
The following snippet of template code would accomplish this dubious task::
{% regroup musicians by instrument as grouped %}
<ul>
{% for group in grouped %}
<li>{{ group.grouper }}
<ul>
{% for musician in group.list %}
<li>{{ musician.name }}</li>
{% endfor %}

As you can see, ``{% regroup %}`` populates a variable with a list of
objects with ``grouper`` and ``list`` attributes. ``grouper`` contains the
item that was grouped by; ``list`` contains the list of objects that share
that ``grouper``. In this case, ``grouper`` would be ``Guitar``, ``Piano``
and ``Trumpet``, and ``list`` is the list of musicians who play this
instrument.
Note that ``{% regroup %}`` does not work when the list to be grouped is not
sorted by the key you are grouping by! This means that if your list of
musicians was not sorted by instrument, you'd need to make sure it is sorted
before using it, i.e.::

and this app's URLconf is included into the project's URLconf under some
path::
